Just responding to this point first, because we need to be rather clear
on the point.  We are not trying to 'clone' AD (in particular, there is
no aim at duplicating the internal structure), and while a goal of
Samba4 is to implement management and logon protocols used in AD, the
server-side design is quite different. 

The closely integrated KDC is not that way 'because Microsoft did it
that way' (their KDC is different again), but for other reasons:

 - A more global design decision was taken describing how Samba4 would
operate as a unix service (as a single binary, providing all integrated
 - Because of the pain in doing portable dlopen() based plugins
 - Because of the close integration between the protocols we support
forced a common backend, and above two points clearly suggested a direct
 - Because it must 'just work', without the admin every knowing what
kerberos is.  

In the long term, I see optional integration with other kerberos
projects as a viable and valuable option, but I'm keen to finish the
current KDC, and gain some real world experiences before I send
developers on wild goose chases for features we may find we actually
can't use.
